Abstract

Since standard Capon beamformer is suffers from performance degradation in the presence of mismatch of the array steering vector of the desired signal. A new robust Capon beamforming algorithm based on the steering vector uncertainty set is investigated. By utilizing the noise subspace obtained by the eigen factorization of the correlation matrix, the projection of signal steering vector onto noise subspace is made to optimize. And an optimal solution of the diagonal loading is derived. The simulation results demonstrate its correctness and effectiveness.
